AI Technical Summary
Traditional damping spring shock absorbers cannot adapt to vibration requirements under different loads and speeds, and have problems such as insufficient damping or excessive stiffness. They are also prone to local resonance and unstable damping adjustment due to uneven force, which can cause the resonance amplitude to soar. Pneumatic components are prone to blockage, and dust can easily cause airway blockage. They also cannot provide real-time feedback or long-term stability.
A single-phase motor drives the turbofan head to generate airflow. The damping force is infinitely adjustable by regulating the air pressure of the airbag through a multi-way solenoid valve and air passage. Combined with real-time monitoring and feedback from the air pressure controller, along with a flexible contact design and spring stiffness adjustment, it avoids unilateral force offset and resonance. Dual filtration prevents blockage, and electromagnetic adsorption gear transmission is used to precisely control the spring stroke.
It achieves precise quantitative adjustment of damping force, reduces resonance and noise, ensures uniformity and stability of shock absorption, prevents blockage of pneumatic components, provides real-time feedback and long-term reliability, and avoids secondary resonance caused by excessive spring stretching and metal collisions.

Description
Technical Field
[0001] This invention relates to the field of damping spring shock absorber technology, specifically to an anti-resonance adjustable damping spring shock absorber. Background Technology
[0002] Currently, damped spring shock absorbers are shock absorption devices that combine spring and damping structures. They are mainly used for vibration isolation, noise reduction, prevention of resonance, and equipment protection. Traditional shock absorbers have fixed, non-adjustable damping, making them unsuitable for the vibration requirements of equipment such as fans, pumps, and motors under different loads and speeds. Fixed damping can lead to insufficient or excessively stiff damping, as well as issues like unilateral load distribution and resonance amplification in the damping components. Furthermore, traditional single-point damping is prone to localized resonance due to uneven stress, and there's a risk of resonance amplitude spikes due to attempts to suppress unilateral load distribution. This results in damping adjustments being prone to decay and inconsistent damping. Traditional hydraulic / mechanical damping adjustment is prone to loosening and damping value drift, and it cannot provide real-time feedback on problems during use. Therefore, it cannot guarantee long-term damping stability. This can lead to problems such as pneumatic component blockage and frequent failures under harsh working conditions, as well as the possibility of airway blockage caused by high dust levels in industrial environments.

[0012] Compared with the prior art, the beneficial effects of the present invention are: This invention uses a single-phase motor to drive a turbofan head to generate airflow, which is then injected into the contact airbag through a multi-way solenoid valve and a multi-way air passage. After the contact airbag expands, it abuts against the movable plate. The damping force can be directly and steplessly adjusted by controlling the air pressure inside the airbag. The air pressure controller monitors the airbag pressure in real time and feeds it back to the control center, achieving precise quantitative adjustment of the damping. The higher the air pressure, the greater the damping, and vice versa. The contact airbag and the mounting spring are evenly distributed around the mounting plate and the movable plate, so the shock absorption force is evenly distributed, avoiding local stress concentration caused by unilateral force deviation. This invention also uses a spring to assist in the reset of the abutment airbag, ensuring the reversibility of the damping adjustment. The bottom of the mounting plate is made of silicone material with a notch design, which flexibly contacts the mounting base, weakens the rigid connection between the base plate and the mounting surface, blocks the transmission of external base vibration to the shock absorber, and reduces resonance superposition. The air intake filter plate of the convergence frame and the working filter plate of the fixed frame double filter the airflow impurities, preventing dust and debris from clogging the multi-pass air passage or damaging the abutment airbag, and preventing the pneumatic adjustment mechanism from failing. This invention simultaneously drives the gear and rotating wheel to rotate via a rotating rod, and the winding connecting rope pulls the moving block and docking sleeve frame downwards. This stretches the spring coil to increase the effective working length and reduces the spring's elastic stiffness. Conversely, fixing the spring and resetting it can shorten the spring length and increase its stiffness, achieving stepless adjustment of the spring stiffness. The fixed electromagnetic block is linked to the rotating rod via an electromagnetically attracted gear. The gear and the docking teeth of the rotating wheel mesh precisely, ensuring a gapless and slip-free transmission. The spring stretching stroke is precisely controllable. The downward movement of the moving block compresses the pressure control switch, feeding back the spring stretching pressure to the control center in real time. This allows for precise limit adjustment of the stroke, preventing the spring from overstretching and breaking. The bottom of the working rod is made of rubber, flexibly contacting the inner cavity of the docking sleeve frame to eliminate internal secondary resonance and noise caused by rigid collisions of metal parts.

The top of the spring ring 7 is connected to the bottom end of the top plate 3. A working rod 8 is movably installed in the middle of the top plate 3. The bottom end of the working rod 8 passes through the middle of the spring ring 7 and connects to the inner cavity of the docking sleeve frame 9. The bottom end of the installation sleeve 2 is made of silicone material and has a notch. The adjustment mechanism 4 includes abutment airbags 408. Several abutment airbags 408 are installed on opposite sides of the mounting sleeves 2 on both sides, and the end of the abutment airbag 408 away from the mounting sleeve 2 is connected to the movable plate 6. Several mounting springs 409 are installed at equal intervals around the abutment airbags 408 on opposite sides of the mounting sleeves 2 on both sides, and the end of the mounting spring 409 away from the mounting sleeve 2 is connected to the movable plate 6.
[0017] A fixing frame 401 is installed on both sides of the top of the fixed base plate 1. A multi-way solenoid valve 402 is provided at the upper end of the inner cavity of the fixing frame 401. One side of the multi-way solenoid valve 402 is connected to the mounting sleeve 2. A gathering frame 403 is installed at the bottom of the multi-way solenoid valve 402. A single-phase motor 406 is installed on both sides of the top of the fixed base plate 1 inside the fixing frame 401. A rotating rod 410 is installed at the top of the single-phase motor 406. Two turbine fan heads 404 are installed at the top of the rotating rod 410 inside the gathering frame 403. A working filter plate is installed on the rear side of the fixed frame 401, and air intake filter plates 405 are installed on both sides of the bottom end of the gathering frame 403.

The rotating rod 410 drives the turbine head 404 to rotate in the inner cavity of the gathering frame 403, and airflow is formed in the inner cavity of the gathering frame 403. The airflow is delivered to the inside of the multi-way air passage 407 through the multi-way solenoid valve 402, and then delivered to the inside of the contact airbag 408 at each position, causing the contact airbag 408 to expand. The air pressure then presses against the mounting sleeve 2 to adjust the damping. The air pressure controller at each position provides feedback, and the control center tells the staff that when the pressure at each contact position is insufficient, the air pressure should continue to be applied. After the air pressure delivery is completed, the multi-way solenoid valve 402 is closed to prevent leakage of the delivered gas.
[0018] The adjustment mechanism 5 includes a connecting frame 501, which is installed at the bottom of the docking sleeve frame 9. A movable block 513 is movably installed in the inner cavity of the docking sleeve frame 9. The movable block 513 has a T-shaped cross-section and a disc-shaped top. Pressure control switches 514 are installed on both sides of the bottom of the inner cavity of the connecting frame 501, and the pressure control switches 514 are electrically connected to an external control center. Connecting ropes 502 are installed on both sides of the bottom of the movable block 513. A fixing spring 515 is fitted onto the bottom of the outer side of the movable block 513. Gears 503 are installed in the middle of the rotating rod 410. Adsorption metal layers 511 are installed around the middle of the inner cavity of the gear 503. Two mounting slots 512 are opened on the rotating rod 410 at the corresponding positions of the adsorption metal layers 511. Fixed electromagnetic blocks 510 are installed in the inner cavity of the mounting slots 512. The fixed electromagnetic blocks 510 are electrically connected to the external control center. The mounting sleeve 2 is equipped with a fixed bracket rod 507 on the lower middle part of the side near the fixed frame 401. The top of the fixed bracket rod 507 is equipped with an electromagnetic bushing 505. A rotating wheel 504 is installed on the outside of the electromagnetic bushing 505. The bottom of the mounting sleeve 2 on both sides is provided with a movable through hole 506 with an inclined structure. The ends of the two connecting ropes 502 away from the moving block 513 pass through the bottom of the mounting ring frame 10 and the inside of the movable through hole 506 and are wound around the outside of the rotating wheel 504. The electromagnetic bushing 505 is electrically connected to the external control center. Several mating tooth blocks 509 are installed at equal intervals on the top and bottom of the rotating wheel 504. The gear 503 meshes with the tooth blocks 509 and the tooth grooves formed between the tooth blocks 509. The mounting ring frame 10 has movable holes on both sides of the bottom end. Several round beads are installed at equal intervals around the bottom of the outer perimeter of the docking sleeve frame 9. The upper perimeter of the inner cavity of the mounting ring frame 10 is equipped with an annular baffle. The bottom of the working rod 8 is made of rubber. The rotating wheel 504 has a mounting round opening 508 in the middle. The mounting round opening 508 fits inside the electromagnetic shaft sleeve 505. The specific implementation method is as follows: When further adjustment of the damping is required, the fixed electromagnetic block 510 is activated to generate magnetism, which magnetically attracts the surrounding absorbing metal layer 511. This drives the gear 503 to rotate via the rotating rod 410. Through the meshing action with the mating tooth block 509, the rotating wheel 504 rotates, winding and collecting the connecting rope 502. During the collection of the connecting rope 502, the moving block 513 moves downwards. When the top of the moving block 513 reaches the bottom of the connecting frame 501, it drives the mating sleeve 9 to move downwards, thus stretching the spring coil 7 and increasing its working length. When block 513 moves downward, it compresses the fixing spring 515. Later, the compressed fixing spring 515 drives the moving block 513 to reset, and the downward movement of the moving block 513 compresses the pressure control switch 514. The pressure generated during operation is fed back to the external control center to inform the staff. If the pressure is insufficient, it is adjusted. After the connecting rope 502 is wound and collected, the electromagnetic bushing 505 is activated to generate magnetism, which attracts and fixes the metal layer installed inside the mounting round opening 508, improving the firmness of the connecting rope 502 after winding and moving, and avoiding the problem of backsliding.
[0019] Working principle: When adjusting the damping during use, the single-phase motor 406 is started to drive the rotating rod 410 to rotate. The rotating rod 410 drives the turbo fan head 404 to rotate in the inner cavity of the gathering frame 403, forming an airflow in the inner cavity of the gathering frame 403. The airflow is delivered to the inside of the multi-way air passage 407 through the multi-way solenoid valve 402, and then delivered to the contact airbag 408 at each position, causing the contact airbag 408 to expand. The air pressure then presses against the mounting sleeve 2 to adjust the damping. The air pressure controller at each position provides feedback, and the control center tells the staff that if the pressure at each contact position is insufficient, the air pressure should continue to be applied. After the air pressure delivery is completed, the multi-way solenoid valve 402 is closed to prevent leakage of the delivered gas. When further adjustment of the damping is required, the fixed electromagnetic block 510 is activated to generate magnetism, which magnetically attracts the surrounding absorbing metal layer 511. This drives the gear 503 to rotate via the rotating rod 410. Through the meshing action with the mating tooth block 509, the rotating wheel 504 rotates, winding and collecting the connecting rope 502. During the collection of the connecting rope 502, the moving block 513 moves downward. When the top of the moving block 513 reaches the bottom of the connecting frame 501, it drives the mating sleeve 9 to move downward, thus stretching the spring coil 7 and increasing its working length. When moving downwards, the fixed spring 515 is compressed. Later, the compressed fixed spring 515 drives the moving block 513 to reset, and the downward movement of the moving block 513 compresses the pressure control switch 514. The pressure generated during operation is fed back to the external control center to inform the staff. If the pressure is insufficient, it is adjusted. After the connecting rope 502 is wound and collected, the electromagnetic bushing 505 is activated to generate magnetism, which attracts and fixes the metal layer installed inside the mounting round opening 508, improving the firmness of the connecting rope 502 after winding and moving, and avoiding the problem of backtracking.
